My FIL insists that I have to do a self assessment this year, although I haven't managed to get the reasons from him. Anyway, I tried to do it online and I need to have a UTR. I've looked through all my papers and there's nothing with a UTR on it. I've tried calling the number given and it's always busy, and you can't do rang back on it, surprise, surprise.
I'm am not self-employed. Does anyone know anything about this?
Thanks.
